       6. The cleaner according to  claim 2 , further comprising a connection elastic member configured to enable the connection rotating shaft moved to the second position to elastically return to the first position. 
     
     
       7. The cleaner according to  claim 1 , wherein the rotating shaft installing part comprises an elongated hole and the connection rotating shaft is movable along the elongated hole of the rotating shaft installing part. 
     
     
       8. The cleaner according to  claim 7 , wherein the rotating shaft installing part is inclined with respect to a surface. 
     
     
       9. The cleaner according to  claim 1 , wherein
 the dust collection unit comprises a button member configured to press a part of the connection member to rotate the connection member, and 
 the button member is configured to press the part of the connection member and move from a first button position to a second button position if the button member receives an external force and the dust collection unit remains on a ground surface. 
 
     
     
       10. The cleaner according to  claim 9 , wherein
 if the connection rotating shaft is provided at the second position, the button member is fixed at the first button position regardless of whether the button member receives the external force. 
 
     
     
       11. The cleaner according to  claim 9 , wherein the button member and the connection member are separate members. 
     
     
       12. The cleaner according to  claim 9 , wherein the dust collection unit comprises a button elastic member configured to enable the button member moved to the second button position to elastically return to the first button position. 
     
     
       13. The cleaner according to  claim 1 , wherein the dust collection unit comprises a dust collection unit gripping part configured to enable a user to grip the dust collection unit to separate the dust collection unit from the main body or to lift the main body and the dust collection unit from a surface. 
     
     
       14. The cleaner according to  claim 13 , wherein if the main body and the dust collection unit are lifted from the surface by an external force applied to the dust collection unit gripping part, the connection rotating shaft moves from the first position to the second position. 
     
     
       15. The cleaner according to  claim 14 , wherein
 the dust collection unit comprises a button member provided at a part of the dust collection unit gripping part, and configured to be movable to rotate the connection member, and 
 if the connection rotating shaft moves to the second position, the button member is fixed. 
 
     
     
       16. A cleaner, comprising:
 a main body; 
 a dust collection unit which is attachable to and detachable from the main body; 
 a rotating shaft provided at a rotating shaft installing part in the dust collection unit, the rotating shaft being configured to be movable between a first position of the rotating shaft installing part and a second position of the rotating shaft installing part; 
 a connection member configured to enable the dust collection unit to be attached to and detached from the main body according to a rotation of the connection member with respect to the rotating shaft, the rotation of the connection member being dependent upon a position of the rotating shaft within the rotating shaft installing part; and 
 an insertion part into which at least a part of the connection member is inserted to attach the dust collection unit to the main body, 
 wherein 
 when the rotating shaft is provided at the first position, the connection member is rotatable, and 
 when the rotating shaft is provided at the second position, rotation of the connection member is restricted so that the connection member is prevented from being rotated around the rotating shaft to thereby prevent the dust collection unit from be detached from the main body. 
 
     
     
       17. The cleaner according to  claim 16 ,
 wherein 
 when the rotating shaft is provided at the first position, the rotating shaft is disposed at an upper portion of the rotating shaft installing part, and

       18. The cleaner according to  claim 17 , further comprising:
 a button member provided at the dust collection unit, 
 wherein 
 when the rotating shaft is provided at the first position and a force is applied to the button member, the connection member is separated from the insertion part to detach the dust collection unit from the main body, and 
 when the rotating shaft is provided at the second position and a force is applied to the button member, the connection member remains in contact with the insertion part to prevent the dust collection unit from being detached from the part of the main body. 
 
     
     
       19. An apparatus comprising:
 a main body including a suction fan configured to intake air and debris into the main body; 
 a dust collector connectable to the main body to complete a path of the air through the apparatus, and to separate the debris from the air when connected to the main body; and 
 a connector configured to connect the dust collector to the main body, and including:
 a shaft, and 
 a connection member slidably and rotatably provided around the shaft, and configured to slide on the shaft between
 a first position where the connection member is rotatable around the shaft to allow the dust collector to be separated from the main body, and 
 a second position where the connection member is prevented from being rotated around the shaft to prevent the dust collector from be separated from the main body.
